Boot-ckimping machine



UNITED STATES PATENT OFFICE.

J. G. BAKER, JR., OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO J. G. BAKER, JR., AND CHARLES BRADFIELD, OE PHILADELPHIA, PENNSYLVANIA.

BOOT-CRIIVIPING- MACHINE.

Specification of Letters Patent No. 16,670, dated February 17, 1857.

To all whom it may concern:

Be it known that I, J. G. BAKER, of the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Crimping Books; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part thereof, in which- Figure 1, represents a perspective view of the machine, and Fig. 2, represents a vertlcal transverse section taken through the machine.

Similar letters where they occur in the separate figures denote like parts of the machine in both.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawrepresents the base of the machine, from which rise the two upright pieces B, B, which are firmly supported by a cross beam C, and an arched, or curved piece D, near their tops. On a plate E, att-ached to the base A, and cross beam C, is formed a hub or boX F, through which passes a shaft Gr, having a crank I-I, on one end and a beveled pinion I, on its other end, which pinion takes into a bevel wheel J, placed on the lower end of the screw shaft or rod K. The screw of this rod K, takes into a block or screw nut L, which can slide up or down on guides M M, said guides M, also serving as braces and supports, between the arched piece D, and cross beam C, upon which the power of the machine is mainly expended.

To lugs a, a, a, a, Xed to the block or screw nut L, are hinged the arms N, N, of the clamps O, O, said clamps being held together by an adjusting rod or bar P, extending from one to the other, and said rod or bar P, should be so united to the clamps, as to admit of ready detachment, when the crimped leather is to be taken out of the machine.

The top edge of the arched or curved piece D is rounded or grooved out, so as to receive the rounded edge of the tree, or former Q, around which the leather R, to be crimped is placed and the shape of the top part of the piece D, should correspond in reverse to that of the tree or former Q. Upon the tree or former Q, are fixed two studs or stops b, Z2, against which the points of the thumb screws S, S, take said thumb screws passing through cross heads T, T, which are rigidly held by the stay rods U, U, that are connected to the cross beam C, by swiveling legs c, c, so that when the leather is crimped and ready to be removed, the thumb screws S, S, and the one V, on the rod or bar P, are simply loosened, and the former with its finished front may be readily taken out of the machine and another as readily introduced. The length of the thumb screws, and the screws cut upon the ends of the rods U, adapt the machine to any size of former. When the former with the leather is properly placed in the machine, the crank H is turned which forces first the points l of the clamps against the leather, and as the clamps or jaws incline both ways from the point d, they smooth and carry out to the edges of the leather any crease or wrinkle that may arise in the process, leaving the leather perfectly formed and smooth, and with the greatest despatch.

Having thus fully described the nature of my machine for crimping boots, what I claim therein as new and desire to secure by Letters Patent is- The combination of the swiveled stay rods U, with their cross heads T, and thumb screws S, when arranged with the former Q, as herein stated, for the purpose of facilitating the removal of the finished boot front, and introduction of another piece, as

herein represented.
